Fully-automatic slicing machine for embedded slice machining

Abstract

The invention provides a fully-automatic slicing machine for embedded slice machining. The fully-automatic slicing machine for embedded slice machining comprises a bottom plate, a supporting plate, an X-axis assembly, a Y-axis assembly, a Z-axis assembly, an embedding shaft assembly, a bathing pool, a housing and a microelectronic control chip. The microelectronic control chip is used for controlling the mutual linkage among the components to complete the slicing action, so that a high automation degree is achieved. A stepping motor and a lead screw are used for matched transmission in the X-axis direction and the Z-axis direction, compared with original matched transmission of a gear and a rack, the structure of the fully-automatic slicing machine for embedded slice machining can more accurately control the cutting thickness and the cutting speed of the slicing machine, and is high in controllability, low in operation noise and stable in operation. A bathing pool is designed to be of a T-shaped structure, so that a culture solution in the bathing pool can be effectively prevented from permeating outwards, the cleanliness of the slicing machine in the slicing machining process is guaranteed, and waste of the culture solution is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of medical and life science experimental instruments, in particular to a full-automatic slicer for embedded slice processing. Background technique [0002] In the field of medical, biological and life science experiments, for the convenience of observation, a microtome is often used to make tissue slices from the sample to be tested for research. The microtome is mainly used in the following two aspects: on the one hand, it is applied to ultra-thin sections of embedded paraffin and frozen tissues, which are used for morphological research of tissues after sectioning; on the other hand, it is used for sectioning of fresh biological tissues. [0003] At present, the embedded microtome on the market has a low degree of automation, most of which are manual or semi-automatic, not only complex in structure, but also cumbersome to operate and low in efficiency. In addition, the Z-axis cutting direction of the exis...

Problems solved by technology

[0003] At present, the embedded microtome on the market has a low degree of automation, and most of them are manual or semi-automatic. Not only the structure is complicated, but also the operation is cumbersome and the efficiency is low.

In addition, the Z-axis cutting direction of the existing embedded microtome uses a DC servo motor to cooperate with the rack and pinion to realize linear movement for slice processing speed control, which makes the cutting speed control accuracy low, and the gear teeth Long-term meshing of the strips will cause wear and tear, which will affect the control accuracy and generate greater noise
